The BL20 concept

The modular concept of BL20: gateway,block and slice design, is a combination ofmany benefits which, as one, represent acompletely new approach to quality in theI/O field. The BL20 gateway means thatI/O modules are no longer dependent onthe type of fieldbus. Its function is to pro-vide communication between the fieldbusand the I/O modules. The DIN-rail mount-able base modules, available in block orslice design, represent the connectionlevel for the field devices. The electronicsmodules, also available as block or slice,are pluggable, and contain the channelfunctions. The power distribution module(24 V DC or 120/230 V AC) supplies theinterconnected I/O with the required volt-age. Bus-independence, precise project planning (you only purchase the requirednumber of channels), the high-level ofcompactness, the list is endless. In short:openness and flexibility are BL20'sstrengths.

BL20 and PROFIBUS-DP

Decentralized periphery

Optimized for high speed, this PROFIBUSversion is designed especially for communication between automation control systems and decentralized periphery devices. PROFIBUS-DP can beused to replace cost-intensive, parallelsignal transmission from digital and analogue sensors and actuators.PROFIBUS-DP is based on DIN 19 245Part 1 and Part 4. During the course ofthe European fieldbus standardization,PROFIBUS-DP has been included in theEuropean fieldbus standard EN 50170.

Topology

PROFIBUS-DP communicates via ashielded twisted pair cable according tothe RS 485 standard. The network topology represents a linear structure withactive bus termination on both ends.

Maximum system extension without repeaters

A PROFIBUS-DP bus line consists of atleast a master and a slave. Without a repeater, a PROFIBUS-DP bus line canconsist of up to 31 slaves.

The maximum number of 32 bus stationsmust not be exceeded without the use ofa repeater!

Maximum system extension with repeaters

A maximum of 3 repeaters can be usedwithin a PROFIBUS-DP structure. Thisincreases the number of possible slavesto 122.

The maximum number of 125 bus stations, including all slaves and repeaters, must not be exceeded!

The PROFIBUS-DP addresses 000, 126and 127 are reserved and must not beused for BL20!

PROFIBUS-DP system extension – BL20 station

Maximum system extension BL20 station

A BL20 station can consist of a gatewayfor PROFIBUS-DP and a maximum of 74slice modules (approximately 1 m lengthof rail including end bracket and endplate). With the use of block modules, themaximum number of modules is corre-spondingly reduced (1 block module cor-responds to approximately 8 slice modules).

Ensure that a sufficient number of PowerFeeding or Bus Refreshing modules areused if the system is extended to its maxi-mum.

BL20 and CANopen

Bus system CANopen

CANopen is a network that is based onthe serial, two-wire transfer of ControllerArea Networks (CAN).

CANopen uses the international CANstandard ISO 11 898 as the basis forcommunications with an open network.This standard covers layers 1 and 2(physical and data link layer) of theISO/OSI communication model. Building on this, the CANopen family ofprofiles were developed by the interna-tional user and manufacture organizationCiA (CAN in Automation). This family of profiles comprises, on theone hand, the communication profile CiADS 301, which represents ISO/OSI layer 7(Application Layer) and which specifies thecommunication mechanisms. And on theother hand, a number of device (CiA DS40x) profiles which specify the device unctionality.

Maximum bus length

The maximum bus length for CANopen is dependent on the rate of transmission:

Mixed operation with other devices

Within a CANopen structure, BL20 can beused in conjunction with CANopen con-form field bus devices from various manu-facturers.

Maximum system extension

A CANopen bus line consists of at leasttwo stations. These could be a PC orPLC, and a BL20 gateway, for example.

A bus line can consist of a maximum of110 stations (for example, BL20 gate-ways).

The use of repeaters can become neces-sary with bus lengths of more than 1 000m.

The CANopen Address 000 is reserved fortelegrams to all stations and must not beused as a station address!

Topology

CANopen is based on a linear topologyutilizing shielded, twisted-pair cabling withbus terminators at both ends of the busline in accordance with ISO-DIS 11 898.

BL20 and DeviceNet

Bus system DeviceNet

The open, low-end network, DeviceNet, isbased on CAN technology.

The communication profile used by BL20 contains:

• UCMM

• Offline Connection Set

• Polled I/O

• COS/Cyclic

• Bitstrobe

• Device Heartbeat Message

• Device Shut Sown Message

The user can select a master/slave, multimaster or a combined configuration, de-pending on application requirements.

Mixed operation with other devices

Within a DeviceNet structure, BL20 canbe used in conjunction with standardizedDeviceNet fieldbus devices from variousmanufacturers.

Topology

DeviceNet uses a full trunk / branch line topology with up to 64 nodes.

Maximum system extension

The branches can be up to 6 m (20 ft) long,but the total extent of all branches dependson the baud rate.

A DeviceNet bus line consists of a scannerand at least another bus station.

The maximum number of 64 bus stations (including the scanner) must not be exceeded.

DeviceNet system extension - BL20 station


BL20 system extension

General system supply

The power supply to a BL20 station is fed via Power Feeding or Bus Refreshingmodules, the latter also being responsiblefor the power supply to the internal mod-ule bus.

Bus Refreshing modules are used within aBL20 station (without gateway supply) ifthe system supply to the BL20 modules(nominal current IMB ≥ 1.5 A) is no longersufficiently guaranteed.These Bus Refreshing modules are to be combined with the base modules BL20-P3T-SBB-B or BL20-P4T-SBBC-B (ten-sion clamp connections) or with the basemodules BL20-P3S-SBB-B or BL20-P4S-SBBC-B (screw connections).

Power Feeding modules are used if thesystem supply to the BL20 modules(nominal current IEL ≥ 10 A) is no longersufficiently guaranteed.

System supply BL20 gateway

The first module on a BL20 station afterthe BL20 gateway must always be a BusRefreshing module as well as the corre-sponding base module BL20-P3x-SBB orBL20-P4x-SBBC with tension clamp orscrew connection to supply the gateway.

Nominal current consumption

The following table offers an overview ofthe nominal current consumption of the if-ferent BL20 modules on the module bus:

≤ 32 mA≤ 32 mA≤ 33 mA≤ 39 mA≤ 43 mA

≤ 28 mA≤ 28 mA≤ 28 mA< 40 mA

System supply via module bus

The number of BL20 modules that can be supplied by a Bus Refreshing module viathe internal module bus depends on therespective nominal current IMB of the indi-vidual modules on the module bus.

The sum total of the nominal current in-puts of the connected BL20 modulesmust not exceed 1.5 A.

The power requirements of the BL20gateway supplied via the first BusRefreshing module in the station is to be isto be taken into consideration when calculating the required number of BusRefreshing modules.

If the software I/Oassistant is used, anerror message is generated automaticallyvia the <Station - Verify> as soon as thesystem supply via the module bus in nolonger sufficiently guaranteed.

All Bus Refreshing modules used in aBL20 station are to be connected via thesame frame potential.

The power supply to the module bus isfed via the connections 11 (plus) and 21(ground) of the respective base module forthe Bus Refreshing module.

Creating potential groups

Both Bus Refreshing modules as well asPower Feeding modules can be used tocreate a potential group.

The potential isolation of the potentialgroup on the left-hand side of the respec-tive power distribution module is createdby the base module.

It is not permitted for modules with 24 VDC and with 120/230 V AC field supply tobe used in a joint potential group.

Therefore, it must be observed that whenusing digital input modules for 120/230 VAC the Power Feeding module BL20-PF-120/230VAC-D is to be used to create aspecial potential group.


BL20 system supply

Acces to the C-rail

Access to the C-rail is be made via basemodules with a C in their designation (forexample, BL20-S4T-SBCS). The corre-sponding connection level is indicated onthese modules by a thick black line, whichis continuous on all base modules forBL20 I/O modules. With base modules forpower distribution modules, the black lineis above the connection 24 only. Thismakes clear that the C-rail is separatedfrom the adjoining potential group to itsleft.

It is permitted to load the C-rail with amaximum of 24 V! Never with 120/230 VAC.

The C-rail can be used as required in the application, for example, as a protectiveearth (PE). In this case, the PE connectionof each power distribution module mustbe connected to the mounting rail via anadditional PE terminal, which is availableas an accessory.

Using the C-rail with relay modules

The C-rail can be used to supply a com-mon voltage when relay modules are tobe used. To accomplish this, the load voltage (24 VDC) is connected to a power distributionmodule with the base module BL20-P4x-SBBC with either tension clamp or screwconnection. All the following relay modulesare supplied with 24 V DC via the C-rail a.

The cross-connection of the individualrelay modules is achieved using the cross-connector QVR b.

If the C-rail is to be used for the joint sup-ply of voltage to relay modules, then theremust subsequently be a further power dis-tribution module used for the potential iso-lation of the following BL20 modules.

The C-rail can again be put on other uses (for example, as a PE) once the potential isolation has been made.

C-rail (cross connection)

The C-rails run through all I/O base mod-ules. The C-rail of the base modules for power distribution modules is mechanically sepa-rated; thus potentially isolating the adjoin-ing supply groups.

Using the C-rail as a protectiveearth

The C-rail can be used as required in the application, for example, as a protectiveearth (PE). In this case, the PE connectionof each power distribution module mustbe connected to the mounting rail via anadditional PE terminal, which is availableas an accessory.
